When accessing the Facebook App Dashboard, then going to Alerts -> Inbox, the panel where the notifications showed is not showing anymore (the content is blank). I attached a print.
The url is: https://developers.facebook.com/apps//alerts/inbox/?business_id=
This started happening after the Business Verification of our App was approved (it might be a coincidence, tough).
This is a live app. This doesn't happen to our 2 development apps (the notifications are loaded correctly).
I cleaned cookies and the storage, but it does not seem to be a cache issue. This issue happens both in Edge as well as Chrome in my machine (Windows 11). To make sure, I asked another coworker and this also happens in his machine, with his (a different) account.
This does not seem to be account, machine or browser specific, although it might be app specific.
Because of this issue, we are not able to see the notifications (it's happening for about a week, we tought that it might be a temporary bug with Facebook, but it wasn't solved in more than a week, so I created this post).
